Before beginning this story, however, it is important to understand how scientists define the concept of race. How is race defined in biological terms? What do we mean by the term race when describing population variation in large mammals such as humans? Do the criteria used in describing these variations hold when we examine human population variation?

In biological terms, the concept of race is integrally bound to the process of evolution and the origin of species. It is part of the process of the formation of new species and is related to subspecific differentiation. However, because conditions can change and subspecies can and do merge, this process does not necessarily lead to the development of new species.

In biology, a species is defined as a population of individuals who are able to mate and have viable offspring; that is, offspring who are also successful in reproducing. The formation of new species usually occurs slowly over a long period of time.

For example, many species have a widespread geographic distribution with ranges that include ecologically diverse regions. If these regions are large in relationship to the average distance of migration of individuals within the species, there will be more mating, and thus more exchange of genes, within than between regions.
